Like Chillblast's Fusion Carbine, the Yoyotech Warbird Titanium Pro SLI uses a pair of nVidia graphics cards to accelerate gaming speeds. This time we find two MSI-branded GeForce GTX 660 Ti cards. These are faster than the entry-level 650 Ti Boost cards used by Chillblast. Together they form a formidable graphics sub-system which delivered very noticeable performance gains in all tests, except Final Fantasy XIV at its highest-quality settings where results were more average.

One of three systems housed in the Corsair Carbide 300R system case, the Warbird Titanium Pro SLI looks, externally, very familiar. Blue interior lighting shines brightly through the transparent side panel, through which all of those expensive internal components can be seen clearly.

In addition to two graphics cards, you get a 3TB hard disk, and 120GB Samsung 840 SSD to boost performance. The system also features built-in 802.11n Wi-Fi.

External components are rather less impressive, because there aren't any. Pay careful attention when considering the cost of this PC as the £1300 Yoyotech is asking for this model doesn't include any peripherals such as monitor, keyboard and mouse.

Add decent examples of these and you're looking at at least another £200 on the price tag, making it one of the most expensive of the group. Also note that this system comes without a Blu-ray drive. It's not an essential for just gaming use, but it's conspicuous when it's the only system here that omits what can be a useful asset. See all gaming PC reviews.

This is an impressively fast PC which overclocks the Core i5-3570K processor from 3.4GHz to 4.8GHz without any signs of over-stretching itself. At £1300, it may look competitive, but you'll need to add in the cost of a monitor, keyboard and mouse before you compare it against other systems in the group test.

A small form factor gaming PC that offers superb all-round PC performance, the Yoyotech Warbird RS2 doesn't come cheap. Read PC Advisor's Yoyotech Warbird RS2 review to see if it is worth the investment.
